of twelve years, it blew 126 days each year, from Odober until 

 May, from fome fouth point, namely, 86 days from the fouth or 

 fouthweft, and 40 from the fouth-eaft, at Abo, lat. 60". 



It is true, that he found it to take place very frequently alfo in 

 fummer, but this is occafioned by the great heat that then prevails 

 in the northern trads of Lapland. 



And, upon the whole, more of the fouth air is drawn ofFin win- 

 ter than in fummer, for its flow is gentle in fummer, but often 

 ftormy in winter. ' See Leflce's IX. XI. and XII. tables. If all 

 other meteorological tables of a feries of years had been arranged 

 with equal fagacity and precifion as thofe of Leche and Dr. Horfe- 

 ley, a vaft fund of information might be extraded from them. 



At Peterfburgh, during the year 1793, Euler junior found a 

 fouth or fouth-weft wind prevailed 79 days, 52 from Odober to 

 the end of March, and only 27 in the fummer months ; it was 

 ftormy in November, December, and January. I have not noted 

 the S. E. • 



Mr. Stritter alfo found the fouth wind to predominate at 

 Mofcow during the fix winter months of that year. 11 N.Ada 

 Petrop. p. 569. So that the frequency of this wind in high lati- 

 tudes is certain.
